Then the Great High comesa partial cancellation of gravitydestroying cities, killing countless people, but the survivors possess strange new telekinetic powers. The old rules are meaningless; anarchy and violence arise, but rationality and cooperation also persist. But with all the old prejudices surviving, humans still turn to military force as the answer to their problems. Can humanity learn to adapt… and survive?
